| 摘要 |
An oxygen enriching module provided with a bundle of many hollow oxygen enriching fibers, each having an air through-passageway enclosed by an oxygen selective permeable membrane wall, a container cell in the shape of a hollow open-ended casing for sealingly encasing the hollow oxygen enriching fibers, an axial air blowing device or air blowing fan integrally connected to at least one end of the container cell to cause an axial flow of the atmospheric air parallel with the axes of the bundle of many hollow oxygen enriching fibers and passing through the air passageways of the bundle of the many hollow oxygen enriching fibers, to thereby obtain an oxygen enriched air from the atmospheric air due to permeation of a part of the atmospheric air through the oxygen selective permeable membrane walls of the hollow oxygen enriching fibers into the chamber of the container cell. A portable oxygen enriching apparatus accommodating the oxygen enriching module provided with a bundle of many hollow oxygen enriching fibers is also disclosed.
